Welcome to the ‘Hazards and Disasters’ online courses. In the three MOOCs which are part of it, we will take a closer look at how remote sensing can answer essential questions related to the emergency response that is needed during hazardous events. Thus, disaster management heavily relies on remotely sensed data and their prompt processing in order to support decisions that can a) estimate the extent of a (natural) disaster and b) save lives by scientifically justifiable choices.
In the three lessons of this course, we will present different applications of remotely sensed data for disaster monitoring to you. At first, we will take a look at droughts, then dive into mapping flood extents using an interactive cloud-based approach before ending our course with the monitoring of fire hazards.
In the lessons listed below, you will be doing the...

For the past ten years, CEMS has provided a global service as a fully operation emergency mapping service at no cost to users and with open access data.
Some highlights on the contribution of CEMS in global disaster risk management activities:

read moreNatural disasters are becoming more frequent and intense across the globe. Enhancing resilience to increasing hazards, exposure, and vulnerability therefore requires leveraging of advanced geospatial technologies for better disaster mitigation and management. With continuous improvements in satellite data sensor acquisition parameters together with geo-computational approaches, geospatial technologies have emerged as the most powerful technology for all phases of disaster management. The course on advanced geospatial technologies for Disaster Risk Reduction (DRR) is scheduled from April 18 - 29, 2022 .
According to a report by the UN Environment Programme (UNEP) and the Norwegian GRID-Arendal organization climate change and land-use change may increase wildfire intensity and frequency globally to unmanageable levels this century. The experts forecast a global increase of extreme fires up to 14% by 2030, 30% by 2050, and 50% by the end of the century. It is hardly unexpected, given how destructive wildfires have become in recent years. A reduction in greenhouse gases will not stop the projected uncontrolled increase in wildfires, experts say. Moreover, the study indicated that wildfires and climate change are "mutually exacerbating" each other, and communities are unprepared for the increased threat of wildfire.
The experts indicate that there is a need for drastic changes in government expenditure on wildfires and encourage investing in prevention and preparedness rather than focusing on reaction and...

Desde 1999, la Comisión Nacional para el Conocimiento y Uso de la Biodiversidad (CONABIO) empezó a utilizar las tecnologías de información y comunicación para desplegar información sobre incendios forestales de manera más sistemática. Además, inició esfuerzos para establecer un Sistema de Alerta Temprana para tales Incendios Forestales (SATIF). La meta de SATIF es generar y proporcionar geoinformación derivada de datos satelitales para el monitoreo y alerta temprana de incendios forestales, que contribuya a conservar la biodiversidad y salvaguardar la vida humana. SATIF está estructurado en base a tres sistemas:
Fires continue to destroy thousands to hundreds of thousands of hectares of forests and wildlands around the world every year. As a first step to address the challenges of wildfires, it is important to assess their geographical location and their severity. This information can be useful to implement restrictions on land use and to identify measures to ensure the recovery of such wild areas.
The Global Wildfire Information System (GWIS) is a joint initiative of the Group on Earth Observations (GEO) and Copernicus Work Programs. In 2021, GWIS launched its Country Profiles application which provides national-level statistics and historical data of fires, including yearly burned area by landcover class statistics generated from MODIS and ESA land cover products.
The historical data included in...
